" CREAM-MEASURING DEVlCE.

SPECIFICATION forming part of Letters Patent No. 284,{l93, datedSeptember 4, 1883.

.To aZZ whom it mag concern:

Be it known that we, WILLIAM W. Soorr and SUMNER A. EMERSON, of Algona, in the county ofKossuth and State of Iowa, have invented a OreamMea-suring Device for Milk Cans, of whi oh the following is aspecification.

The object of our inventionis to provide a simple device that is complete in itself, and

specially adapted for measuring the depth of It consists in forming atubular transparent device, as hereinafter fully set forth, in such a manner that it can be gently introduced in v the open top of the can, to float in the cream and milk without injury to the cream by moving or agitating into. serve as a graduated measure through which the thickness or depth of the cream and its increase will be plainly visible to the naked eye as long as .the'device is allowed to float in milk and cream.

Figure 1 of our accompanying drawings is a side view, Fig. 2 is a transverse section, and

Fig. 3a perspective view, of our cream-measuring device. Fig. 4 is a sectional view of a milk-can, showing our device floating in the cream and milk. Jointly considered, these figuresclearly illustrate the construction, ap plication, and operation of our invention. V

' A represents a transparent glass vessel, preferably of angular shape, six-and a half (65-) inches long, three (3) inches wide from top to bottom at two of its sides, three-fourths (2) of an inch wide at the top, and half an inch at the bottom-of its other two sides. It is open-at its top and widest end and closed at its narrow bottom. On one or both of the narrow sides of this wedge-shaped tubular and transparent device we form or attach a scale or inch-measure, B, by forming a raised or sunken surface in the glass by means of a suitable mold or die, by cutting andxengraving the glass, by printing or painting in colors, by attaching a scale made of paper, sheet metal, orothersuitable material, in such a manner that the figures on the scale B will be plainly visible onthe inside of the glass, and the milk and cream on the outside of the glass Application filed May 8, 1882. (No model.)

I also plainly visible and distinguishable from each otherfrom the inside of the glass when the device is placed in the milk and cream ended vessel.

In the practical use of our invention thus constructed, we simply place one in each milkcan in the dairy, after it has been filled lower and contractedend sink downward from the surface of the milk until the top is nearly on a level with the surface of the milk. When in this position it will float and require no further attention, and as the cream'forms and rises around the floating measure it will anchor it, and the thickness or depth of the cream can be readily determined at all times bysim ply looking in the top of the vacant and transparent device to see at what point on the scale B the dividing-line between the cream and the milk crosses the scale. If p the device and scale B extend half an inch above the top surface of the cream, and the dividing-line between the cream and the milk is at 4% on the scale, it is obvious that the cream is four inches thick on top 'of the milk. Anydepth or thickness of cream in a can will be thus readily determined without disturbing the cream; or, if the cream has formed before the measuring pressed down through the cream to determine its depth, and then again withdrawn without agitating, stirring, or injuring the cream.

We are aware that lactometers for ascertaining the specific gravity and value of milk, and lactoscopes for determining the amount of cream in'milk by ascertaining its degree of opacity, havebeen made of transparent glass tubes,'and that glass vessels have had measuring-scales formed on or in their surfaces to be used as graduated measures by pouring be inserted in a milk-can, to remain vacant and afloat for the purpose of measuring cream, is novel and greatly advantageous.

We are aware that a sheet-metal vessel having a glass fixed in its side and a scale of measurement on the glass, and provided with a weights, has been used for measuring cream but our device, formed complete in one piece with fresh sweet milk, by gently letting the device was inserted, the device can be readily contained in a can or other suitable openfluids into them; but our device, adapted to 1 v Ico chamber at its bottom filled with suitable in the manner contemplated by our invention;

of transparent glass, and weighted by simply from its top end downward, substantially as making the bottom thick, is novel and greatly set forth.
